- Backend computes time-domain RMS, maps -60..-6 dB to 0..1, sends as `level` alongside the per-frame-normalized frequency bins. - Frontend prefers `level` directly; drops the peak-of-bins fallback and the redundant volume-slider attenuation (loopback capture is already post-volume on Windows/macOS).
